What is different about the 5th edition? The best of the previous edition is still there though in some places condensed a little to make room for newer information. Basic facts unfold in both text and pictures, making the information easier to understand. Many new photographs, some of them in color, have been added to old favorites in black and white.Topics included are: choosing a rabbit, handling, housing setups, bunny proofing, exercise, toys, house training, behavior, bonding, diet, and medical care. As in previous editions, caregivers across the continent have shared their recent discoveries and insights.
